Hypoactivity following perturbed estrogen signaling in the medial amygdala.
Activation of estrogen receptor α (ERα) in the brain prevents obesity as the result of increased energy expenditure and decreased food intake. While ERα is present on several neural populations, it is not clear how different regions of the brain mediate the weight-regulating effects of ERα activation. In this issue of the JCI, Xu and colleagues provide extensive evidence that ERα is abundant on...
متن کاملEstrogen receptor-α in medial amygdala neurons regulates body weight.
Estrogen receptor-α (ERα) activity in the brain prevents obesity in both males and females. However, the ERα-expressing neural populations that regulate body weight remain to be fully elucidated. Here we showed that single-minded-1 (SIM1) neurons in the medial amygdala (MeA) express abundant levels of ERα. Specific deletion of the gene encoding ERα (Esr1) from SIM1 neurons, which are mostly wit...
متن کاملEstrogen-induced alteration of mu-opioid receptor immunoreactivity in the medial preoptic nucleus and medial amygdala.
The mu-opioid receptor (mu-OR), like most G-protein-coupled receptors, is rapidly internalized after agonist binding. Although opioid peptides induce internalization in vivo, there are no studies that demonstrate mu-OR internalization in response to natural stimuli. In this study, we used laser-scanning microscopy to demonstrate that estrogen treatment induces the translocation of mu-OR immunor...
متن کاملEstrogen Receptor-α in the Medial Amygdala Prevents Stress-Induced Elevations in Blood Pressure in Females.
Psychological stress contributes to the development of hypertension in humans. The ovarian hormone, estrogen, has been shown to prevent stress-induced pressor responses in females by unknown mechanisms. Here, we showed that the antihypertensive effects of estrogen during stress were blunted in female mice lacking estrogen receptor-α in the brain medial amygdala. Deletion of estrogen receptor-α ...
متن کاملEstrogen receptors in the medial amygdala inhibit the expression of male prosocial behavior.
Studies using estrogen receptor alpha (ERalpha) knock-out mice indicate that ERalpha masculinizes male behavior. Recent studies of ERalpha and male prosocial behavior have shown an inverse relationship between ERalpha expression in regions of the brain that regulate social behavior, including the medial amygdala (MeA), and the expression of male prosocial behavior. These studies have lead to th...
